SCHÖKEM injection attachment for permeating cohesive soils with a cement suspension

The SCHÖKEM process is a system of soil stabilisation using an excavator attachment to inject and mix a defined concrete suspension in non-load bearing soils (KSI) that, when left to harden, create a homogenous, impermeable and frost resistant soil-cement structure. Depending on soil conditions and desired load bearing requirements, various concentrations of cement and binder fluid are used.

The new SCHÖKEM injection attachments are available in two sizes for mounting on excavators between 35 and 80 ton operating weight and can be supplied with a range of blade lengths. The drive unit for the KSI 5000 can work with blades for 3, 4 and 5 m mixing depths and the larger KSI 10000 with blades for mixing depths of 6, 8 or 10 m. Both models can be supplied with a rotation module as an optional extra.

  • Mixing blade extendable to 10 m
  • The attachment can be mounted on standard excavators
  • Optimal pattern of tungsten carbide tipped tools for the mixing process
  • High torque drive motors provide enough power to mix heavy soils
  • Simple, heavy-duty construction
  • Hydraulic tensioning of the mixing chain is possible
